Abstract: A cyclone (500) suitable for use in a third stage separator in a fluid catalytic cracking unit or to improve other gas/solid separations. The cyclone has an inlet for gas and entrained solids (515) and a clean gas outlet tube (520) at one end of a cyclone body. Solids and some gas are withdrawn through a solids outlet (545) and discharged into a catch chamber. Some of the gas discharged with the solids into the catch chamber is returned to the interior of the cyclone body through a gas reflux opening in the cyclone (555). Chaotic reflux of gas back into the cyclone through the solids outlet is eliminated.

Patent CA-2261834-A1 (CA)
Inventor: SWINIMER KIRK
IPC: E04G13/00
Filed: 1997-07-16
Abstract: A prefabricated form for molding a footing of a settable structural material at the bottom end of a tubular form (10) for a structural pillar is disclosed. The form (10) is preferably constructed from a thermoplastic such as a high density polyethylene or ABS and is molded as a single disposable unit. The form (10) is bell-shaped and has a sidewall (12) which is inclined at an angle of about 45° to about 65° with respect to the bottom edge. A top flange (22) of the form is preferably adapted to accommodate two or more different diameters of the tubular form for the structural pillar. The sidewall may include integral ribs (28) which open inwardly to facilitate evacuation of air as the form (10) is filled and to lend rigidity to the sidewall (12) to ensure that it will not collapse if earth is backfilled around the form before the form (10) is filled with settable material. The advantage is an inexpensive form which fills reliably without the entrapment of air pockets, supports a tubular form for a pillar without cross-pieces, may be left in the ground and actually protects the footing from the intrusion of water, etc. Thus significant savings in labour and a significant improvement in the quality of footings for structural pillars made using tubular forms is realized.
